It also helps if you know which kibble is your hedgie's favourite.
My boy LOVES his NB Green pea & duck, and will always eat it first and finish it before moving onto his Wellness. And so, I'll poke open a capsule and drop onto only the NB and make sure those get a good soaking. This ensures that he gets pretty much the entire capsule of flax seed.
And I also feed it once a week. Though when he has really dry skin, partway into the week, I'll open another capsule and split the oil. Half directly on his back, and half in his food.
